  • FIGS. 8 to 11 are views similar to FIGS. 4 to 7 but indicating further variations of the construction of a nozzle regulating tube.
  • FIGS. 8a, 9a, 10a, and 11a are diagrammatic plan views of the sprinkling areas which are effected by the various arrangements of regulating tube indicated in FIGS. 8 to 11 inclusive.
  • the linkage is adjustably connectable to the crank arm 7 at its one end and connected to the nozzle assembly 20 at its opposite end; and, when it is driven by the crank arm, it oscillates the assembly backwardly and forwardly about the axis YY.
  • the eccentric mechanism defined by the connection of the link 6 to the crank 7 is adjustable for example, with four eccentric settings and thus four different fields of traverse or with an intermittently variable setting.
  • the housing I includes a foot portion or pedestal 5 for supporting it in the upright position indicated in FIG. I and it is closed on the delivery end by a cover 4.
  • the nozzle assembly 20 includes the guide sleeve I4 which has a plurality of orifices or openings 15 defined along its length which are opened at the interior and which communicate individually with individual discharge passages 17 which are formed in a nozzle body 12, and which, for example, may be made of a plastic material but which has a geometric form such as a circular segment.
  • the nozzle body 12 may advantageously be applied over the guide tube 14 by cladding.
  • a feature of the construction of the nozzle body is that a central discharge passage 17' is arranged to extend substantially vertically and the passages on either side thereof, that is, the passages 9, 9 and 17 diverge outwardly from the central passage, for example at varying angles.
  • the inlets of all of the discharge passages communicate with respective orifices 15. With such an arrangement the spray pattern may be extended from one end to the other end of the regulating tube.
  • the discharge passages are all each provided with a brass nozzle fitting or nozzle member 13 so enhance the formation of jets and the radiation of the sprinkling water.
  • a regulating sleeve or regulating member 10 is arranged within the guide sleeve 14 and it is advantageously rotatably supported within a female thread II at an end fitting of the tube 14.
  • the regulating sleeve 10 includes a knob portion 10' which extends outwardly from one end and it includes an opposite opened end which communicates with the water supply through a fitting 8 of the housing 1.
  • the outer shell surface of the regulating sleeve bears on the inner shell surface of the guide sleeve 14 in such a way that the movement of the water between the regulating sleeve 10 and the guide sleeve 14 is prevented.
  • the regulating sleeve 10 can be turned relative to the guide sleeve by overcoming a certain frictional resistance.
  • the water which passes from the house supply through the connection 2 and the turbine 3 is discharged through the fitting 8 into the interior of the regulating sleeve 10 and it moves outwardly through a selected set of openings or slots 16 through the orifices and it is discharged through the passages 9, 9' and 17, 17' and through the brass nozzles 13.
  • the regulating sleeve 10 may be provided with one or more patterns or aperture arrangements around its periphery which in the embodiment shown comprises four separate patterns arranged along a longitudinal line at 90 intervals around its periphery.
  • a pattern 16 which comprises a single longitudinally elongated slot.
  • FIG. 5 showing the sleeve 10, includes a further regulating area or pattern 16a which is advantageously located at some angle from the area 16 for example at 90 away from the slot 16.
  • the openings which extend through the regulating sleeve 10 are arranged centrally in respect to the length of the regulating sleeve so that the full area shown in 4a will not be covered but only a partially reduced rectangular area as indicated in 5a will be covered. 7
  • the inventive device may be further modified, for example as indicated in FIGS. 8 to 11, by providing a regulating tube or sleeve member 10' having patterns 16', 16a 16b and 160, respectively.
  • the pattern 16' shown in FIG. 8 produces a sprinkling effect on two outer rectangular areas leaving a cen tral rectangular area which is not sprinkled as indicated in in FIG. 8a.
  • a variation of this arrangement is indicated in FIG. 11a where the central area is sprinkled but the outer areas are not.
  • FIGS. 9a and 10a show the use of the devices with the pattern 16a and 16b respectively which cause a sprinkling of one side or the other of the normal sprinkling area.
  • FIGS. 4a to 110 are to show schematically the manner in which the sprinkler may be regulated for controlling the sprinkle pattern but of course may other variations would be possible.
  • Each pattern control is located on a separate longitudinal generatrix, for example, the line a-a of FIG. 7, line b-b of FIG. 6, etc.
  • These generatrices are respectively aligned with the openings 15 in order to position the selected patterns in the operative position and indications of the generatrices are advantageously carried on the knob 10 to indicate when the various patterns are aligned in an operative position.
  • the regulating sleeve 10 permits not only a variation of the length of the sprinkling area but also a fine adjustment of the strength of the jet issuing from the nozzle holes. This occurs when the patterns, such as the slots 16 are oriented so that they are offset slightly from perfect alignment with the openings 15 so that there is a reduced flow area communication between the interior of the regulating tube with its water supply and the apertures 15. A spray mist is obtained for example with minimum overlapping of the opening 16 with the orifices 15. This possibility of dosing the water jet is of great practical importance. For some soils the full jet is too strong and would result in a deterioration of the soil structure or a mudding action. In this case regulation of the water jet can remedy the situation.
  • sprinkling area remains unchanged to increase or decrease the sprinkling density which is also possible with the present invention.
  • a garden requires spraying with very fine droplets instead of a full jet such as a vegetable garden.
  • a full jet is required. It is even possible to spray plants subject to intensive solar radiation, in order to reduce their evaporation.
  • the regulation of the sleeve it permits adaptation of the device to the allowable water consumption and to the existing water pressure conditions are providing the same number of active nozzles or sprinkling areas.
  • the nozzle assembly is indicated as being adaptable to oscillate about a horizontal axis but the arrangement of the invention can also be used with an oblong nozzle rotating about a vertical axis. With such an arrangement, the guide sleeve 10 would still have openings mounted within a guide tube in a manner such that the openings may be selectively oriented for the desired pattern arrangement.
  • the nozzles need not be limited for arrangement where there is linear water flow.
  • the nozzle can also be designed as an arcuated tube provided on the top side with a number of orifices and which is mounted for rotation about a horizontal axis. With such an arrangement the dosing nozzle must be flexible.
